Prep for tiling on wooden floor

[xeres]

Diynot

Ok tilers, need your help for some prep work to fit tiles in an open plan kitchen which runs into a soon to be carpeted lounge area. The key thing I'm trying to achieve is having as small a step as I can dr the tile to the carpet!

It's a first floor flat in an old Georgian townhouse conversion. I understand I have a couple of options:

1.
Rip up floorboards and replace with t&g 18mm chipboard for flooring. Sheet with 6mm wbp ply and tile.

2.
Rip up floorboards and replace with wbp 24mm ply (Would this need noggins?)

Want this to be done right once by myself an this is a first. Any and all of your input appreciated.

If your using a decent flexible adhesive like BAL flex then I would use 18mm WBP leaving a 1 inch expansion gap around the perimeter screwed down at 150mm centres.

Depending on the size of the area you may need an expansion joint in the tiles.

If you contact one of the manufactures of adhesive and tell them what you intend to do, they will tell you exactly how to prepare the sub surface for they're product.

just to point out, dont take your first option, its just not right. if overboarding you need at least 12mm, or a cement tile backerboard
